as shown in fig. 6, the cap chuck 5 includes a cap holding portion and pin portions for inserting pins into the respective cords; the lamp cap clamping part is used for clamping and sleeving the lamp cap 11 on the lamp holder 12; the pin part has the moving and/or rotating functions, is used for correspondingly inserting the pins into the flexible wires respectively, and guides the flexible wires to move towards corresponding positions through the pins, so that the subsequent flexible wires are conveniently compressed and fixed:
and a sheath cutting mechanism for cutting the sheath of the cord end as shown in fig. 5.
In the above embodiments, the cap assembling device of the LED bulb lamp is used to assemble the cap 11 and the base 12 of the LED bulb lamp shown in fig. 1. The cap 11 before assembly is a metal screw 111 as one input electrode of the power supply, and an insulating core 112 with a central hole is installed in the center, and the metal central core 13 is inserted into the central hole as the other input electrode of the power supply. A power supply board 123 of the bulb lamp is assembled in the heat radiator 124 of the lamp holder 12, and 1 power supply cord, namely a center cord 121 connected with the metal center 13 and a screw cord 122 connected with the metal screw 111 of the lamp cap 11, is welded on each of the two poles of the power supply input end of the power supply board 123. In the process of assembling the cap 11 of the LED bulb lamp to the lamp holder 12, it is critical to ensure reliable connection between the center cord 121 and the metal center 13, and between the screw cord 122 and the metal screw 111.
In the above embodiment, the limiting elastic member is connected between the positioning portion of the lamp holder clamping mechanism 2 and the wire end clamping portion, so that when the wire end clamping portion rotates relative to the positioning portion, two limit positions of opening and working are formed, when the wire end clamping portion is located at the working position, the wire end clamping portion is matched with the sheath cutting mechanism to complete cutting, and when the wire end clamping portion is located at the opening position, the operating space of the lamp cap clamping mechanism 5 is made free.
As shown in fig. 3, the positioning portion includes a bottom plate 26, a positioning counterbore is formed in the middle of the bottom plate 26, lamp holder clamping jaws 24 are formed along the circumference of the positioning counterbore, and each lamp holder clamping jaw 24 is connected with the bottom plate 26 through an elastic member. One side of the bottom plate 26 is connected with a chuck limiting frame 23; the wire end clamping part comprises a flexible wire clamping jaw 21, and one end of the flexible wire clamping jaw is rotationally connected with a chuck limiting frame 23; the limiting elastic part adopts a limiting spring 22 connected between a chuck limiting frame 23 and the flexible wire clamping jaw 21, and the limiting spring 22 provides self-locking torque for positioning the flexible wire clamping jaw 21 at two limiting positions.
In one particular form, three socket jaws 24 are circumferentially distributed around the locating counterbore and are supported by jaw springs 25 for gripping the socket 12. The cord gripper 21 is used to grip the ends of the shaped center cord 121 and the screw cord 122 so that they can maintain a relatively controllable position in the subsequent lamp cap clamping process. The flexible wire clamping jaw 21 can swing around the chuck limiting frame 23, the two swinging limit positions are the opening position and the working position of the flexible wire clamping jaw 21 respectively, and the reliable self-locking of the respective positions is ensured by the limiting spring 22. When the cord gripper 21 is in the working position, the gripper is used for clamping the shaped central cord 121 and the screw cord 122; when the cord jaws 21 are in the open position, the jaws are flipped outwardly to allow room for the lamp base 12 and cap 11 to move up and down. Specifically, the diameter of the positioning counter bore is slightly larger than that of the lower opening of the lamp holder 12, and a positioning support plate is arranged in the counter bore; the opening in the lampholder clamping jaw 24 is beveled. Therefore, when the lamp holder manipulator grabs the lamp holder 12 and inserts the lamp holder 12 into the counter bore from top to bottom, the edge of the lower opening of the lamp holder 12 can automatically push the lamp holder clamping jaw 24 open, and the lamp holder 12 is fixed on the lamp holder clamping mechanism 2. The clamping of the base 12 may take a variety of different mechanical configurations. As an illustration of the lamp holder fixture 2, the three-jaw clamping structure described in this example is only used to explain the clamping principle, but not to limit the clamping mechanism of the present invention.
In the above embodiment, as shown in fig. 4, the wire arranging part includes the side wire arranging fork 31 and the front wire arranging fork 32, the front wire arranging fork 32 is provided with a plurality of slots respectively matched with the cords, the side wire arranging fork 31 has a through slot for simultaneously limiting the cords therein from the side, and the side wire arranging fork 31 and the front wire arranging fork 32 position and clamp the cords in the mutually perpendicular directions and then move along the axial direction of the cords to straighten the cords.
As a specific form, the side wire-arranging fork 31 and the front wire-arranging fork 32 are arranged in a vertical crossing manner, the front wire-arranging fork 32 horizontally enters from the direction vertical to the power supply board 123, the two power cords are limited at the roots of the two power cords, the side wire-arranging fork 31 horizontally enters from the direction parallel to the circuit board, the front wire-arranging fork 32 is later forked at the lower part of the front wire-arranging fork 32, the front wire-arranging fork 32 and the side wire-arranging fork 31 jointly limit the two cord frames in two small frames, and the cords in the limit frames are shaped and straightened by moving upwards synchronously. After reaching the upper end of the flexible wire, the flexible wire clamping jaw 21 turns over to enter a working position to clamp the ends of the two flexible wires, so that the ends of the flexible wires are positioned. In the figure, the broken line and the solid line respectively represent the position of the wire arranging component in the process of action and the position of the wire arranging component in the position of action, and the arrow direction represents the action direction of the wire arranging component.
In the above embodiment, as shown in fig. 5, the sheath cutting mechanism includes a set of sheath cutters 41 that are engaged with each other to cut the sheaths of the respective cord ends that have been straightened, from both sides, respectively.
The sheath cutter 41 cuts two parallel edges of the upper end sheath of the cords 121 and 122 held by the cord gripper 21. In the subsequent process, the sheath wire of the tip can be directly pushed and pulled out at an appropriate time, so that the metal wire for connecting with the electrode is exposed. In this station two sheath cutters 41 are cut into the cord from the horizontal, as shown in figure 5, and the portion of the sheath of the end remains on the cord after the cutting is complete. In the figure, the broken line and the solid line respectively indicate the position and the cutting position during the operation of the sheath cutter 41, and the arrow direction indicates the operation direction.
As shown in fig. 6, the number of the pin parts is two, and each pin part is provided with a pin position; the two pin positions are provided with pins which are respectively butted with the core flexible wire 121 and the screw flexible wire 122 on the lamp holder 12; one of the pin positions is arranged on a rotating arm 54 which rotates at least 90 degrees, the rotating arm 54 drives the end part of the screw soft wire 122 to move through a pin to realize bending, the other pin position is connected with the lamp cap clamping part and moves along with the lamp cap clamping part, and the structure of the lamp cap clamping part comprises a lamp cap clamping jaw 52. As a specific form, the cap gripper 52 is used as an executing end of the cap grabbing manipulator, the top of the cap gripper is provided with a pin part, a pin position on the pin part is loaded with a center cord pin 51, when the cap gripper 52 grabs the cap 11 and the lamp holder 12 to be sleeved, the axis of the center cord pin 51 is coaxial with a center hole of an insulating core 112 of the cap 11 and a center cord 121 on the lamp holder clamping mechanism 2, so that the center cord pin 51 can penetrate through the center hole of the insulating core 112 and be vertically inserted into an upper end head sheath hole of the center cord 121; the pin position on the rotating arm 54 is loaded with a screw soft wire pin 53 which is also inserted into the upper end head sheath hole of the screw soft wire 122 in the vertical direction, and after the end head connection is completed, the soft wire clamping jaw 21 can loosen the soft wire end head and turn to the open position, so that the up-and-down assembling space required by sleeving the lamp cap is saved. The power cord is sleeved on the needle point of the contact pin due to the friction force between the needle point and the inner hole of the sheath. Thus, when the cord jaws 21 are released and turned to the open position to allow room for the cap to fit, the power cord can not only remain in place, but also change the position of the tip as the pins move. The screw cord pin 53 rotates with the pin rotating arm 54 to move the end of the screw cord 122 to the upper edge of the heat radiator 124 of the lamp holder 12, i.e., to bend to a position close to horizontal in the figure. When the lower edge of the metal screw 111 is sleeved on the upper edge of the heat dissipation body 124 from top to bottom, the upper edge of the heat dissipation body 124 pushes down the end sheath of the screw cord 122 to expose the end metal wire of the screw cord 122, and the metal wire is clamped in the shaft hole plane matched with the two edges. During the downward movement of the cap 11 and socket 12, the cord pins 51 guide the cord 121 through the holes in the cap insulator 112 and expose the ends.
In the above embodiment, as shown in fig. 7 to 9, the riveting device further includes a dotting riveting mechanism, a sleeve removing mechanism and a core inserting mechanism; the dotting riveting mechanism comprises a dotting needle 61 for dotting riveting on the assembled lamp holder 12 and the lamp cap 11; the sleeve removing mechanism comprises a sleeve removing push plate 71 used for removing the sleeve of the flexible wire end cut by the sleeve cutting mechanism; the core plug mechanism comprises a core clamping jaw 81 for inserting the metal core 13 into a corresponding position on top of the lamp cap 11.
Based on the lamp cap assembling method of the lamp cap assembling equipment of the full-automatic LED bulb lamp assembling line of the embodiment, the assembling equipment comprises a lamp holder clamping mechanism 2, a flexible wire shaping mechanism 3, a lamp cap clamping mechanism 5, a sheath cutting mechanism, a dotting riveting mechanism, a sleeve removing mechanism and a central core inserting mechanism; the lamp holder clamping mechanism 2 is fixed on a circulating conveying chain or a rotary disc to circulate, and is matched with other mechanisms respectively on respective corresponding stations of lamp cap assembly equipment to complete the lamp holder clamping, flexible wire shaping, sheath cutting, lamp cap sleeving, dotting and riveting, flexible wire sleeve removing and center plugging processes in sequence, and an intermittent indexing mechanism is adopted to introduce the process flow based on the equipment:
lamp holder clamping: the lamp holder clamping mechanism 2 serves as a station pallet of the lamp cap assembly device, and the flexible wire clamping jaws 21 of the lamp holder clamping mechanism are in an open position at the beginning of the assembly process. At the lamp holder clamping station, the lamp holder manipulator takes off the lamp holder 12 from the feeding frame and moves to the mounting position, namely, right above the central counter bore of the lamp holder clamping mechanism 2. When the lamp holder clamping mechanism 2 reaches the clamping station along with the equipment rotating disc or the circulating transmission chain, the lamp holder manipulator vertically moves downwards. The outer edge of the lampholder first contacts the inner inclined surfaces of the three lampholder jaws 24 of the lampholder fixture 2, pushing the lampholder jaws 24 supported by the jaw springs 25 to spread outwards. When the bottom edge of the lampholder 12 reaches the bottom surface of the central counter-sunk hole of the bottom plate 26, the lampholder manipulator releases the clamping jaws and moves away, and the lampholder 12 is clamped on the bottom plate 26 by the lampholder clamping jaws 24, so that the clamping process of the lampholder is completed. The lamp holder clamping mechanism 2 which completes the lamp holder clamping immediately shifts to the next station, namely the shaping station of the power cord.
Shaping of a flexible wire: the cord shaping mechanism 3 clamps the center cord 121 and the screw cord 122 on the lamp holder 12 by using the cord arranging part and straightens the cords along the cord axial direction, and then the cord end clamping part rotates to the working position relative to the positioning part to clamp the cord ends. Specifically, the front wire-arranging fork 32 of the vertical power supply board 123 firstly enters horizontally from the root of the flexible wires, the side wire-arranging fork 31 of the parallel power supply board 123 enters horizontally along the lower surface of the front wire-arranging fork 32, and crosses the front wire-arranging fork 32 to form two small square frames, two flexible wires are clamped in the small square frames, two sets of wire-arranging forks clamp the flexible wires, and simultaneously move vertically and upwards from the root of the flexible wires, so that the two power supply flexible wires are shaped and straightened, and when the wire-arranging fork group reaches the upper ends of the flexible wires, an external push rod (or other driving structures) pushes the flexible wire clamping jaws 21 on the lamp holder clamping mechanism 2 to inwards turn to the working positions, so that the upper end heads of the two flexible wires are clamped. And the two groups of wire arranging forks are withdrawn to finish the shaping process of the flexible wires. The lamp holder clamping mechanism 2 then enters a sheath cutting station.
Cutting a sheath: the sheath cutting mechanism cuts the sheath of the cord end in a straightened state by using a set of sheath cutters 41 to form a notch. Specifically, the cord gripper 21 still holds the upper end of the power cord, and a pair of parallel sheath cutters 41 are cut into the cord sheath from the horizontal direction, so as to cut a pair of parallel knife edges on the cord sheath, thereby facilitating subsequent sleeve removal. After cutting, the sheath cutter 41 returns along the original path, and the sheath cutting process is completed. The lamp holder clamping mechanism 2 then enters a lamp cap sleeving station.
Sleeving a lamp cap: the lamp cap sheathing process is a core process and is used for completing the connection of the contact pin and the flexible wire end of the lamp holder clamping mechanism 2. The lamp cap clamping mechanism 5 uses the lamp cap clamping portion to send the lamp cap 11 to the upper part of the lamp holder clamping mechanism 2, the two pin inserting portions are respectively connected with the center flexible wire 121 and the screw flexible wire 122 by using pins, then the wire end clamping portion rotates to an opening position relative to the positioning portion, and the pins respectively guide the flexible wires to move towards different directions and complete the sleeve connection of the lamp cap 11 and the lamp holder 12. The lamp cap sleeving station needs to complete more actions. In particular, the cap gripper 52 will perform three actions, the first step being to grasp the cap 11 from its supply rack; the second step is to move the lamp cap 11 right above the lamp holder 12; the third step is to move the lamp cap 11 vertically downwards to be sleeved on the lamp holder 12. In this example, since an intermittent indexing mechanism is employed, the first two actions are typically completed in the indexing stage, with the intermittent stage completing only the third portion of the actions. In the process of sleeving the lamp cap 11 and the lamp holder 12, the upper end of the power cord is driven to move through the contact pin, and each action of the two power cords is completed. The action of the third step is decomposed as follows:
when the lamp cap 11 moves right above the lamp holder 12, the central cord pin 51 mounted on the manipulator where the lamp cap clamping jaw 52 is located passes through the inner hole of the lamp cap insulating core 112 and is inserted into the end inner hole of the central cord 121; at the same time, the screw cord inserting pin 53 mounted on the rotating arm 54 is also inserted down into the end inner hole of the screw cord 122. The flexible wire clamping jaws 21 are released and turned to the open position, so that the lamp cap is arranged in the lamp holder. Then the end of the screw flexible wire 122 is driven by the screw flexible wire inserting pin 53 to turn over, so that the end of the screw flexible wire 122 moves to the edge of the upper edge of the lamp holder, the lower edge of the lamp cap metal screw 111 and the upper edge of the heat radiating body 124 are extruded in the process that the lamp cap 11 is sleeved on the lamp holder 12, the end sheath of the screw flexible wire 122 is extruded and pushed down to expose the metal wire, and the lamp cap 11 continues to move down for sleeving, so that the metal wire is firmly clamped in the shaft hole surfaces matched with the two edges. And the center cord pin 51 simultaneously carries the center cord 121 through the inner bore of the cap insulator 112. And finally, moving out the two flexible wire contact pins to finish the sleeving action of the lamp cap. The lamp holder clamping mechanism 2 then enters a dotting and riveting station.
Dotting and willowing: as shown in fig. 7, the cap 11 and the socket 12 of the socket assembling device may be connected by any riveting method commonly used at present, and the final purpose is to integrally connect the cap 11 and the socket 12. The dotting and riveting process used in this example is only one of these and is only used to illustrate the possibility of achieving a connection of the cap 11 to the socket 12. At the dotting riveting station, a plurality of dotting needles 61 are uniformly distributed along the circumferential direction at the joint of the lamp cap metal screw 111 and the lamp holder 12, the dotting needles 61 synchronously move centripetally along the arrow direction in the figure, a circumferential riveting pit is inwards pressed on the joint ring surface at the lower side of the lamp cap metal screw 111, and the lamp cap 11 and the lamp holder 12 are riveted together by utilizing the metal deformation of the circumferential riveting needles 61. The lamp holder clamping mechanism 2 then enters a flexible wire sleeve removing station.
Removing the sleeve of the flexible wire: the sleeve removing mechanism removes the end sleeve of the central cord 121 along the cut by using the sleeve removing push plate 71, and pushes and bends the end of the central cord 121; as shown in fig. 8, the sleeve-removing push plate 71 horizontally enters above the lamp cap to push and bend the end of the core cord 121 passing through the hole in the insulating core 112 of the lamp cap, and simultaneously push down the sheath of the end to expose the metal wire of the cord for connection with the electrode of the metal core 13.
